High School Math Guide

Creating Equations

Core Guide

Secondary Math I

Create equations that describe numbers or relationships. Limit these to linear equations and inequalities, and exponential equations. In the case of exponential equations, limit to situations requiring evaluation of exponential functions at integer inputs (Standards A.CED.1 – 4). Standard I.A.CED.4: Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations. For example, rearrange Ohm ’ s Law V = IR to highlight resistance R . Concepts and Skills to Master • Extend the concepts used in solving numerical equations to rearranging formulas for a particular variable; limit to linear formulas Related Standards: Current Course Related Standards: Future Courses I.A.REI.3, I.A.REI.5, I.A.CED.1, I.A.CED.2, I.A.SSE.1 II.A.SSE.1, II.A.CED.1, II.A.CED.2, II.A.CED.4, II.F.IF.8, II.G.GMD.1, II.G.GMD.3, III.A.CED.4, III.F.IF.8, III.A.SSE.1 Critical Background Knowledge • Use variables to write equations and solve them (6.EE.2, 6.EE.6, and 6.EE.7) • Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how quantities are related (7.EE.2) • Solve multi-step equations (7.EE.3, 7.EE.4, and 8.EE.7) Academic Vocabulary Constant, variable, formula, literal equation Resources Curriculum Resources: http://www.uen.org/core/core.do?courseNum=5600#70123
